Looking for a Schematic for an Engl Retro Tube 50 model 762

[andywragg]

Hi there

The guitar shop I do repairs for on an ad-hoc basis has got an Engl Retro Tube 50 that they want me to take a look at. A quick google didn't return much other than the operators manual. Can anybody point me in the right direction?


Cheers

Andy
